稻田蜘蛛是害虫的重要捕食性天敌,在我区资源丰富。为了了解蜘蛛在自然生态系中的捕食害虫的情况,以及在人工助迁下抑制害虫的潜力,我们于1980年在本所进行了试验。试验是从5月29日开始的。当日人工作草把插放于正在翻耕而蜘蛛多的麦田,随即灌水,迫使蜘蛛爬上草把栖息。5月30日选条件相同的中稻田8亩(油菜茬口,品种桂朝2号,5月12日栽秧)作为助迁田。助迁田分四个处理区,每个处理区2亩。各处理区先调查蜘蛛和飞虱的基数,方法采用五点
Paddy spiders are important predators of pests, rich in resources in our region. In order to understand the spiders’ predatory pests in natural ecosystems and the potential for controlling pests under manual removal, we conducted our test in 1980. The trial started on May 29. The same day, the working grass inserted into the tillage is plowing more wheat fields, then irrigation, forcing the spiders to climb the grass habitat. On May 30, 8 mu middle-paddy fields (rapeseed stubble, variety Guizhao No.2, planted on May 12) with the same conditions were selected as help-moving fields. Moving to the field four processing areas, each processing area 2 acres. Each processing area to investigate the base of spiders and planthoppers, the method uses five points
